面板51的長邊側會比短邊侧發生更大地勉曲、即，彎曲。 這樣，圖8所示的觸控面板裝置中，壓電元件52所引 起的觸控面板51的彎曲振動方向與手指55的按下所引起 的觸控面板51的撓曲方向一致。因此，在圖9 (b)所示 201218040 38726pif 的觸控面板51的按下狀態下，能夠藉由壓電元件52而使 觸控面板51高效地彎曲振動。而且，觸控面板51因固定 用緩衝物53的彈性變形而發生彎曲，因而與將壓電元件 52配設在觸控面板51的短邊的情況相比，以相同的伸縮 量能獲得更大的振動振幅，從而具有壓電元件52的小型化 或成本降低的優點。 [先行技術文獻] [專利文獻] [專利文獻1]日本專利特開2006-227712號公報 然而，在使觸控面板振動的觸控面板裝置中，有時壓 電元件相對於觸控面板的配設位置會受到限制。例如，在 將圖8所示的長方形狀的觸控面板設為縱長來使用並構成 可攜式終端機的觸控面板裝置的情況下，自小型化或設計 性的觀點考慮，一般來說，成為如下設計：收容觸控:板 的框體的橫寬與框體的縱寬（高度）相比，相對於 板的有效操作區域而無餘裕。 ' 工 因此，若將壓電元件配設於觸控面板的長邊側，則要 增大框體的橫寬，或者，要將觸控面板的有效操作區域的 橫寬對應於壓電元件的寬度進行縮短，從而必需進行嗖叶 以使得壓電元件不會被看見。然而，設想若以此方式構， 則會導致觸控面板裝置的大型化，而破壞設計性。 ^為上述問題的對策，例如，聽相對於觸控面板的 有效操作區域，而在位於有相對的餘裕的框體的高度方向 的觸控面板的短邊侧配設壓電元件。例如，圖8所二的觸 201218040 38726pif 控面板裝置中，設想將壓電元件52如圖平面圖所示， 配設於長方形狀的觸控面板51的短邊側。 然而’如圖10所示般，若僅將壓電元件52配設於觸 控面板51的短邊侧而進行4點支持，則因壓電元件52的 伸縮，觸控面板51如圖11概略立體圖所示，以兩方的長 邊側為關節而發生彎曲振動。其結果，壓電元件52所引起 的彎曲振動方向與圖9 (b)所示的按下所引起的撓曲方向 不同，而壓電元件52所引起的觸控面板51的彎曲振動時 的能量損耗增大，從而擔心無法獲得所期望的振動振幅。 【發明内容】

Description of the Invention: [Technical Field of the Invention] Panel Device Ο The present invention relates to a touch [Prior Art] In recent years, various input devices have been proposed, which detect 3 panels such as an operator's finger or a stylus pen. Vibration gives the operator a sense of operation. For the second device, for example, the following plate device is known as shown in Fig. 8. The work of the rectangular touch panel is: in the direction along the long side: two =:: 4 The corner portion is supported by the fixing cushion (c-), and is flexibly supported by the fixing frame 54 (see, for example, Patent Document 1). In the touch panel device shown in Fig. 8, the piezoelectric elements 52 of the long sides are placed at '. When the telescopic drive is performed in the same direction in the longitudinal direction, the fixing cushion 53 is elastically deformed, and the touch panel 51 has the short sides of both sides as the schematic perspective view of FIG. Bending vibrations occur. Furthermore, such bending vibrations are also referred to as buckling vibrations. Further, as shown in Fig. 9(b), when the touch panel 51 is pressed by the finger 55, for example, the long side of the touch panel 51 is more warped, that is, bent, than the short side. Thus, in the touch panel device shown in Fig. 8, the bending vibration direction of the touch panel 51 caused by the piezoelectric element 52 coincides with the deflection direction of the touch panel 51 caused by the depression of the finger 55. Therefore, in the pressed state of the touch panel 51 of 201218040 38726pif shown in Fig. 9(b), the touch panel 51 can be flexibly vibrated by the piezoelectric element 52. Further, since the touch panel 51 is bent by the elastic deformation of the fixing cushion 53, the same amount of expansion and contraction can be obtained as compared with the case where the piezoelectric element 52 is disposed on the short side of the touch panel 51. The vibration amplitude has an advantage of miniaturization or cost reduction of the piezoelectric element 52. [Patent Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2006-227712. However, in a touch panel device that vibrates a touch panel, a piezoelectric element may be associated with a touch panel. Setting the location will be limited. For example, in the case where the rectangular touch panel shown in FIG. 8 is used vertically and the touch panel device of the portable terminal device is used, it is generally considered to be small or design. The design is as follows: accommodating the touch: the horizontal width of the frame of the plate is less than the effective width of the frame (the height). Therefore, if the piezoelectric element is disposed on the long side of the touch panel, the lateral width of the frame is increased, or the lateral width of the effective operation area of the touch panel is corresponding to the piezoelectric element. The width is shortened so that the crotch leaves must be made so that the piezoelectric element is not seen. However, it is assumed that if it is constructed in this manner, the touch panel device is enlarged and the design is deteriorated. In order to solve the above problem, for example, the piezoelectric element is disposed on the short side of the touch panel in the height direction of the frame having the opposite margin, with respect to the effective operation area of the touch panel. For example, in the touch panel 201218040 38726pif panel device shown in Fig. 8, it is assumed that the piezoelectric element 52 is disposed on the short side of the rectangular touch panel 51 as shown in a plan view. However, as shown in FIG. 10, when only the piezoelectric element 52 is disposed on the short side of the touch panel 51 to perform four-point support, the touch panel 51 is as shown in FIG. 11 due to the expansion and contraction of the piezoelectric element 52. As shown in the perspective view, bending vibration occurs with the long sides of both sides as joints. As a result, the direction of the bending vibration caused by the piezoelectric element 52 is different from the direction of the deflection caused by the pressing shown in FIG. 9(b), and the energy of the bending vibration of the touch panel 51 caused by the piezoelectric element 52. The loss is increased, so that the desired vibration amplitude cannot be obtained. SUMMARY OF THE INVENTION Therefore, an object of the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a touch panel that can flexibly vibrate with a desired amplitude without causing an increase in size of the device and without deteriorating design.

On the touch panel U. The touch panel 11 has four corners on the back side in such a manner that the deflection direction caused by the pressing of the pressing object such as the operator's finger or the stylus pen coincides with the bending direction caused by the expansion and contraction of the piezoelectric element 12 . The portions jla to nd and the corner portions 11a and 11b of the long sides and the total of the corner portions llc and 11d are six places, and are supported by the fixing portion 14 via the elastically deformable supporting members 13a to 13f. In other words, the touch panel 11 is supported by six points by a total of six support members 13a to 13f, and the six support members 13a to 13f are disposed to extend and contract with the piezoelectric element 12 as the short-side direction of the touch panel 11. The direction is disposed more in the direction orthogonal to the direction in which the piezoelectric element 12 as the longitudinal direction of the touch panel 11 is orthogonal. The support members Ua to 13f are illustrated as a columnar shape, but may be of any shape such as a prismatic shape. Further, the fixing portion 14 is formed of, for example, a liquid crystal panel or a display panel such as an organic electroluminescence (EL). Here, the touch panel 11 is shown in the imaginary line of FIG. 1 and includes two sides having a long side of the pain control panel 11 having 201218040 38726pif and two sides of the short side of the touch panel. In the case of the effective operating region τ of the rectangle, the piezoelectric element 12 is preferably provided in a region beyond the effective operating region τ. Moreover, the four corner portions 11a to 11d of the touch panel 11 are preferably formed as an area formed by extension lines of the long side and the short side of the touch panel 11 and the sides of the simple area T (the image) Wire wire)). Further, in the respective regions of the corner portions m to iid, the support members 1Sa to ... supporting the corner portions 11a to 11d are preferably disposed in the respective regions away from the effective operation region T in the respective regions of the corner portions 11a to 11d. Within the area of the corresponding corner. Further, in the respective regions of the corner portions m to Ud, the support members 13a to 13d for supporting the corner portions 11a to 11d are preferably in contact with the long side of the touch panel 11, preferably at the corner portions 11a to 11d. The regions are arranged to be in contact with the long side and the short side of the touch panel u, respectively. Here, when the supporting members 13a to i3d are disposed as described above, the supporting members 13e disposed between the supporting members 13a and 13b are preferably disposed on a straight line connecting the supporting members 13& Further, the support member 13f disposed between the support members 13c and 13d is preferably disposed on a straight line connecting the support members 13c and 13d. Further, in Fig. 1, the case where the ineffective operation area T is a rectangular shape similar to the touch panel u, but may be a square-shaped rectangle. Further, the distances DL1 and DL2 between the support members 13a and 13b of the corner portions 11a and Ub adjacent to each other on the long side of the support member 13e that supports the long sides of the touch panel 11 are It is shorter than DS1 and DS2 from 201218040 38726pif between the adjacent support members 13a and 13d and 13b and 13c which support the corner portions 11a, lid and lib of the two sides of the touch panel 11 in the short-side direction. . Similarly, the support member 13f that supports the other long sides of the touch panel u has a distance DL3 between the adjacent corner portions 11c and the support members i3c and 13d of the lids on the corresponding long sides. DL4 is shorter than the above distances DS1 and DS2. Further, the distance DS3 between the support members 13e and 13f is longer than each of the DL1 to DL4. In other words, the touch panel 11 is respectively adjacent to the four supporting members 13/, 13e, 13f, 13d and 13e, 13f, 13b, 13c in the direction in which the piezoelectric element 12 expands and contracts and in the direction orthogonal to the stretching direction. The support is formed in a rectangular shape in which the stretching direction of the piezoelectric element 12 is a long side. Furthermore, it is preferable that the long sides of the support members 13e and i3f (four) supported between the long sides of the control panel 11 are equally located in the center, and are viewed by the DU as follows: 3 (10) L4 < DS1 and DS2 Tune 3 is set. In the touch panel device of the present embodiment, the two piezoelectric elements 12 disposed on the short side of the touch panel 2 are closed in the direction along the short side of the touch panel u. , _ control panel u as shown in the figure: the schematic perspective view, with the long sides of the two sides as the same: one, and the 'touch panel 11 as shown in Figure 4, the perspective view = large by the finger 15 pressed, the side of the job It will be more than the long side of the hair spot: the bending direction caused by the pressing direction of the pressing object 2, the bending direction caused by the extension of S2, so the side of the figure is equipped with: Thunder? The short side ratio of the rectangular touch panel supported by 2 points is the energy loss when the touch panel 11 t H and f are vibrated as shown in FIG. 4, so that the 201218040 38726pif touch panel n can be piezoelectrically The element 12 efficiently bends and vibrates at a desired amplitude. Further, if the support members 13e and 13f supporting each other between the money of the money panel u are arranged in a reduced manner, the touch panel U II can be made long by the piezoelectric element 12 over the entire length. The side direction is bent in the same manner in the short side direction. Thereby, the effective operation area τ β ' of the touch panel 11 can present substantially the same tactile sensation to the operator. Further, the self-operating panel device has the piezoelectric element 12 disposed on the rectangular shape control panel η. In the case of the touch panel device of the portable terminal, the piezoelectric element 12 can be disposed in a frame height direction with a relatively margin. .

In Fig. 5 (a) and Fig. 5 (b), the tempered glass 23 is made of glass having a short side of 65 mm, a long side of 120 mm, and a thickness of 0.7 mm. Further, each piezoelectric element 12 is made of tempered glass having a short side of 2 mm, a long side of 40 mm, and a thickness of 0.4 mm. Each of the support members 13a to 13f is composed of PORON (registered trademark) H-48 manufactured by ROGERS INOAC, and has a columnar shape of a vertical X-axis X height of 3 mm x 3 mm x 2 mm. Each of the support members 13a and 13d is disposed apart from the short side of the tempered glass 23 by 1 mm in the region corresponding to the corner portions 11a to 13d, and the support members 13e and 13f are disposed on the respective long sides. In the middle, that is, from the short side of the 60mm position. Here, in FIG. 5(a), each of the support members i3a and 13b is disposed to coincide with one long side of the tempered glass 23, and each of the support members 13c and 13d and the other side of the tempered glass 23 are disposed. The long sides are consistently arranged. Thereby, a rectangular shape having the same orientation as that of the tempered glass 23 is formed by the four support points. In addition, in FIG. 5(b), each of the support members 13a, 13b, and 13e on one of the long sides of the tempered glass 23 is disposed so as to coincide with the corresponding long side, and the other long side is similarly Each side of the support members 13e, 13d, and 13f is disposed in correspondence with the corresponding long side. Thereby, two rectangular shapes whose directions are orthogonal to the tempered glass 23 are formed by the four support points in the vicinity, and are arranged in the longitudinal direction of the tempered glass 23. That is, the rectangular long sides and short sides formed by the four support points in the vicinity are formed in the short side direction and the long side direction of the tempered glass 23, respectively. Fig. 6 is a schematic view showing a schematic configuration of an experimental apparatus. The test apparatus 13 201218040 38726pif is used to measure the vibration amplitude _ and the output frequency [Hz] of the central portion of the sample 2 22 reinforced glass 23 by a laser Doppler vibrometer 31. In addition, FIG. 6 illustrates the measurement state of the sample 21. The experimental apparatus includes a mounting table 32 on which the sample 21 is placed, and supports the support table 34 of the mounting table 32 in a displaceable manner in the mounting normal direction via at least two pairs of parallel leaf springs 33, and is mounted in a pair of parallel A strain gauge 35 of the leaf spring 33. In the comparative experiment, the support table 34 was placed on the fixed plate 36, and the support members 13a to 13d or the support members 13a to 13f were placed on the lower side, and the sample 21 or the sample 22 was placed on the mounting table 32. Further, with respect to each of the samples 21 and 22, the vicinity of the central portion of the tempered glass 23 is pressed by a finger, and the pressing load is detected by the strain gauge 35. Further, in a state where the pressing load of 2 [N] is detected, a driving signal is applied to the piezoelectric element 丨 2 to vibrate the tempered glass 23, and the center of the tempered glass 23 is measured by the laser Doppler vibrometer 31.

Further, the driving signal applied to the piezoelectric element 12 is a sine wave obtained by an output frequency of 150 [Hz] to 35 〇 [Hz] exhibiting a better tactile sensation when the operator presses the touch panel. Half the period of the input frequency, the amplitude is set to 4 〇 [γ].

In the touch panel, when the piezoelectric panel is not provided on the short side of the touch panel, the shape formed by the straight line connecting the support points with each side of the m touch panel becomes a rectangular shape in the same direction as the touch panel. In the case of supporting the touch panel at four points of the four corners, the rectangular shape of the orientation of the touch panel is made in the direction of the long side of the panel. At 6:00 to support the bending vibration of the piezoelectric element is reduced enough touch surface due to touch panel, in the known consumption 'thereby obtain a high vibration amplitude. Therefore, it is possible to efficiently bend and vibrate the touch panel with a desired amplitude. The present invention is not limited to the above embodiment, and may be implemented or changed. For example, in the above-described embodiment, the elastic coefficients of the support members 13e and 13f that support the sides of the touch panel 11 are larger than the coefficients of the four corner portions m to ud of the touch panel U that are larger than 15 201218040 38726pif. That is, it can be formed in a manner that is easily elastically deformed. (4) The supporting members..., nf may be formed in a small size, or may be called a supporting material, to make the sectional area; the supporting member 3d has the same sectional area, thereby increasing the piezoelectricity. The vibration amplitude of the touch panel 引起 caused by the component 12. Further, the number of the piezoelectric elements 12 may be one or more. Further, the bending direction caused by the depression of the touch panel 11 can produce a flexural component in the short-side direction. Therefore, the long side members 13e'13f_lla~lld__13a~i3=^ only the end end is in the direction of the short side of the control panel η in the direction of the short side of the touch panel n or the fixed portion M = In the above embodiment, the control panel 1 can be controlled by 6 points. The support member can be configured to enter the sulfur according to the direction of the touch panel u, as shown in FIG. ~13h and 8 points to support or 1G point to support the touch panel η. In other words, the short side (four) of the rectangular touch panel U is disposed in a support point_counter in which the electric component is in the direction of the contraction, and the % is a branch in the direction orthogonal to the expansion and contraction direction of the piezoelectric element. In the above way, the touch panel u is supported by a point of 6 or more points. Further, the present invention is not limited to the rectangular touch panel, and can be effectively applied to a brother who uses a touch panel of any shape. That is, 201218040 38726pif In the present invention, the touch panel has an arbitrary shape, and the support of the touch panel is supported by the manner in which the deflection direction caused by the depression of the touch panel coincides with the bending direction caused by the expansion and contraction of the piezoelectric element. The member is disposed more in the direction orthogonal to the expansion and contraction direction than the expansion and contraction direction of the piezoelectric element. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention.
